摘　　要：介绍了新行业标准中计量统计范围、水量平衡构成要素、漏损率的国内外对比情况。北京市通过水平衡要素分析漏损控制关键点,结合实际选择以独立计量区(DMA)作为重点的分区计量管理;依托管网GIS系统和水力模型系统调整供水调度方案进行压力优化;逐步更换约146万具智能远传水表;建立用户水量远程监测和分析系统;通过暗漏检测、管网改造等减少了管网破损点。上述措施综合施策,使得北京市市区的漏损率连续10年下降,于2020年降为9.93%。The new industry standard was compared at home and abroad in the aspects of metering statistical range,water balance components and water loss rate.The water loss control practices in Beijing mainly includes analyzing water loss and controlling key points through water balance factors,selecting district metering area(DMA)practically,optimizing water pressure through adjusting the regulations of pumps and valves based on GIS system and hydraulic models,gradually replacing 1.46 million smart water meters,developing water consumption remote monitoring and analysis system,and reducing the breaks in pipes through active leak detection and pipe rehabilitation.The above measures resulted in a consecutive reduction of water loss rate in downtown Beijing for ten years,reaching 9.93%in 2020.
